METHOD: This study collected 350 subjects' facial photos in the laboratory environment, who aged 18-60, with blackhead symptoms in the nasal region...

This symposium offered up-to-date perspectives on field experiences and the latest research on significant viral and bacterial diseases affecting poultry. A highlight was the discussion on the use of enteroids as advanced in vitro models for exploring disease pathogenesis. Outcomes of this symposium included identifying the urgent need to improve the prevention and control of avian influenza by focusing research on vaccine effectiveness. In this regard, efforts should focus on enhancing the relatedness of vaccine antigen to the field (challenge) virus strain and improving immunogenicity...

Histomoniasis is a deadly disease of turkeys causing devastating economic losses to the poultry industry. In field outbreaks, a presumptive diagnosis is made based on gross pathology lesions and confirmed by histopathology. An early detection tool with quick turnaround time is needed to prevent the spread of histomoniasis. With this objective, two studies were conducted in turkeys. In Study 1, 40 poults were housed in two pens (20 poults/pen) and challenged at 14 days of age with Histomonas meleagridis by intracloacal route...

A total of 100 589 Chinese males and 1 838 997 Chinese females aged 18 to 85, without facial skin conditions, and who had access to a smartphone with a high-resolution camera all took selfies. METHOD: Using a smartphone application with a built-in artificial intelligence algorithm, facial skin diagnostic evaluated the selfies and score the severity of the dark circles with four other facial indicators (including skin type, Pores, Acne vulgaris, and Blackheads)...

This study provides estimates on genetic parameters, inbreeding depression and purging for meat performance measures from 25 German sheep breeds. All German meat, merino sheep breeds and breeds of other breeding directions with a sufficient number of pedigree and performance data were included in this study. Phenotypic traits retrieved from the national database OviCap were evaluated: daily weight gain, meatiness score and ultrasound measurements for muscle and fat thickness. We employed animal models to estimate heritability, variance and covariance components for these meat performance traits as well as inbreeding depression and purging...

BACKGROUND: Gut infections of chickens caused by Ascaridia galli and Heterakis gallinarum are associated with impaired host performance, particularly in high-performing genotypes. Heterakis gallinarum is also a vector of Histomonas meleagridis that is often co-involved with ascarid infections. Here, we provide a first insight into the alteration of the chicken plasma and liver metabolome as a result of gastrointestinal nematode infections with concomitant histomonosis. 1 H nuclear magnetic resonance (1 H-NMR) based-metabolomics coupled with a bioinformatics analysis was applied to explore the variation in the metabolite profiles of the liver (N = 105) and plasma samples from chickens (N = 108) experimentally infected with A...

A 53-year-old male presented to the clinic for "bilateral temporal dark yellow plaques with pruritus for 8 years." The patient had bilateral temporal dark yellow plaques without obvious inducement 8 years ago and did not see doctors at that time. Five years ago, bilateral temporal skin lesions gradually increased and were accompanied by severe itching. On top of them, there were several blackheads and pimples with the size of needle tips up to the size of rice grains. After compression, lipid substances could be excreted and there was a clear odor...

BACKGROUND: Adolescents who make up a vast majority of the secondary school population are at a stage at which they are largely affected by acne. This condition, which is widely visible and easily recognized by peers, has numerous misperceptions surrounding it, which may influence attitudes toward people affected by it. There is a paucity of information on the prevalence of acne and how adolescents in Jos, Nigeria, view the condition. OBJECTIVE: This study aimed to determine the prevalence of acne, perceived risk factors, and the accuracy of self-report among adolescents in Jos, Nigeria...

BACKGROUND: Histomonas meleagridis can infect chickens and turkeys. It uses the eggs of the cecal worm Heterakis gallinarum as a vector and reservoir. Litter beetles (Alphitobius diaperinus) and other arthropod species have been implicated as potential vectors, but little information about other arthropod species as potential vectors is known. METHODS: Four broiler breeder pullet farms were sampled every 4 months. On each farm, three types of traps were set inside and outside two houses...

Twice-a-year, large-scale movement of billions of birds across latitudinal gradients is one of the most fascinating behavioral phenomena seen among animals. These seasonal voyages in autumn southwards and in spring northwards occur within a discrete time window and, as part of an overall annual itinerary, involve close interaction of the endogenous rhythm at several levels with prevailing photoperiod and temperature. The overall success of seasonal migrations thus depends on their close coupling with the other annual sub-cycles, namely those of the breeding, post-breeding recovery, molt and non-migratory periods...

Intestinal health plays a major role in profitable and efficient turkey production. Blackhead disease (histomoniasis) is caused by Histomonas meleagridis , an anaerobic protozoan parasite. Histomonas meleagridis disrupts intestinal integrity and may cause systemic infection. Some field outbreaks of blackhead disease are associated with low morbidity and mortality, while in some instances, it may cause severe morbidity and mortality. In the current study, a presumptive diagnosis of blackhead disease was made based on the characteristic gross lesions in the liver and ceca...

AIMS: To develop an effective sebum control essence to reduce oiliness of skin. METHODS: The composition of the essence was designed in consideration of different oil control mechanism targets. The skin irritation was assessed in 30 volunteers by a single application close patch test...

Acne vulgaris is a common skin disorder with a complicated etiology. Papules, lesions, comedones, blackheads, and other skin lesions are common physical manifestations of Acne vulgaris , but the individual who has it also regularly has psychological repercussions. Natural oils are being utilized more and more to treat skin conditions since they have fewer negative effects and are expected to provide benefits. Using network pharmacology, this study aims to ascertain if neem oil has any anti-acne benefits and, if so, to speculate on probable mechanisms of action for such effects...

Simple sequence repeats (SSRs), the markers with the highest polymorphism and co-dominance degrees, offer a crucial genetic research resource. Limited SSR markers in blackhead seabream have been reported. The availability of the blackhead seabream genome assembly provided the opportunity to carry out genome-wide identification for all microsatellite markers, and bioinformatic analyses open the way for developing a microsatellite genome-wide database in blackhead seabream. In this study, a total of 412,381 SSRs were identified in the 688...

Acne is a common chronic skin condition with serious physical and psychosocial consequences. In some cases, the appearance of pimples, whiteheads, or blackheads on the face, neck, and back may lead to scarring, disfiguring, depression, frustration, and anxiety in patients. Current treatments rely on antibiotics to eradicate Cutibacterium acnes ( C. acnes ), the bacterium responsible for this skin condition. However, these approaches do not scavenge the reactive oxidative species (ROS) generated during disease development and raise concerns about the increase in antimicrobial resistance...

BACKGROUND: The principal function of skin is to provide a barrier to water loss and percutaneous penetration of exogenous substances. Any compromise of the skin homeostasis can lead to dryness, itchiness, or even pathogenic conditions. This study aimed to explore the relationship among psychological stress, skin homeostasis, sleep quality, and emotion. METHODS: This prospective observational study was conducted using a random sample of medical students from Shanghai Medical College, Fudan University...
